I run mdadm, lvm, and dm-crypt with an initramfs. mdev works fine for all of
those; I haven't tried devtmpfs yet to comment on that.
And I'm pretty sure vgchange/vgscan will (or can be commanded to) create its
own nodes, even without a device manager of any kind.
But in any case you don't need a persistent or custom-configured device manager
to use those features.
